I’m using bio tabs so if it’s nutrient burn I can’t do anything to stop it

To me it looks like nutrient burn not light burn, which would cause the leaves to go brown and crispy.
18/6 is much more plant friendly and a 100 watt light would have to be almost touching the plant to cause burning.
I would be either reducing the feedings or the nutrient strength and would be quite happy to have the light at 100%, it is only 100 watts after all.
Also I would be ensuring there is run off each irrigation, this will help slow the build up of nutrient salts in the substrate.
Hope this helps,..........

Not Nutrient BurnWell I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?

Strange leaf shape, who has encountered this and what came out as a result?1. Am I right that it was just overwatering?
2. Who has experienced the same thing?
3. What are the chances of growing a healthy plant?
I appreciate all the responses, this is very important to me, thank you!

Is this Potassium deficiency? If not, which deficiency is it? Day 99, 39F. Leaves getting a bit yellow, while having browning on the tips.I know that it is not overfeeding, and I also know that it is not lockout. PH could be off, but I do not think so. So, what deficiency is this?
